On the uniqueness of nondegenerate blowups for the motion by curvature of networks

In this note we prove uniqueness of nondegenerate compact blowups for the motion by curvature of planar networks. The proof follows ideas introduced in “Lojasiewicz-Simon inequalities for minimal networks: stability and convergence” for the study of stability properties of critical points of the length functional and it is based on the application of a Lojasiewicz-Simon gradient inequality.
